I want to disable IOAPIC enteries and enable xHCI hand-off in the UEFI. (Also preferably show the settings in the UEFI for on the fly config).

Results: I edited the UEFI with AMIBCP. When I tried flashing with Instant Flash, it gave a security error. I then proceeded to flash with AFUDOS using the command "AFUDOS biosname" However nothing has changed. I tried resetting the defaults and pressing the clear CMOS button but everything is still the same.
